Safety researcher Paul McCarty uncovered a major coordinated spam marketing campaign focusing on the npm ecosystem.
The IndonesianFoods worm, because it has been named, consists of greater than 43,000 spam packages printed throughout not less than eleven consumer accounts over nearly two years.
These packages have survived undetected, representing multiple p.c of the complete npm registry whereas ready for activation.
The marketing campaign’s scope is alarming. A single execution of the malicious script can publish roughly twelve packages per minute, producing round 720 per hour or 17,000 per day.
The assault leverages a intelligent naming scheme that makes use of Indonesian names like “andi” and “budi” mixed with meals phrases akin to “rendang” and “sate,” adopted by random numbers and suffixes like “-kyuki” or “-breki.”
Examples embody packages named “zul-tapai9-kyuki” and “andi-rendang23-breki.” This distinctive sample creates camouflage throughout the repository whereas remaining traceable.
Every package deal seems official on first inspection, containing customary Subsequent[.]js mission constructions with correct configuration information, official dependencies like React and Tailwind CSS, {and professional} documentation.
The malicious element lies in hidden script information named both “auto[.]js” or “publishScript[.]js,” which sit dormant and unreferenced within the package deal construction.
ENDOR Labs safety analysts recognized that these packages have been a part of an assault first described in April 2024, the place attackers abuse the TEA protocol meant for rewarding open supply contributions.
The platform tracks cryptocurrency rewards for ecosystem individuals, which the attackers exploited to monetize their spam marketing campaign.
A minimum of one maintainer seemed to be an Indonesian software program engineer, explaining the regional specificity of this operation.
The Worm’s Self-Replicating Mechanism: How Dormant Code Prompts and Spreads
The IndonesianFoods worm demonstrates a very insidious spreading mechanism by means of dependency chains.
When the malicious script executes manually—triggered by instructions like “node auto[.]js”—it performs three steady actions. First, it removes the “personal”: true flag from package deal[.]json information, a safety builders use to forestall unintended publication of proprietary code.
Second, it generates random model numbers like “2.3.1” to bypass npm’s duplicate detection techniques.
Third, it updates the package deal[.]json and package-lock[.]json information, then runs “npm publish –entry public” to flood the registry with new packages on a seven to ten-second cycle.
What makes this assault significantly harmful is that every spam package deal references eight to 10 further spam packages as dependencies.
When builders set up one contaminated package deal, npm robotically fetches its total dependency tree, doubtlessly pulling in over 100 associated spam packages in cascade.
Putting in a single package deal might expose techniques to exponential proliferation of malicious packages throughout the registry.
A few of these packages gathered 1000’s of weekly downloads, creating alternatives for attackers to inject precise malicious code in future updates affecting huge numbers of installations.
The monetization side by means of TEA token rewards demonstrates attackers are incomes cryptocurrency by means of synthetic ecosystem worth, with some packages overtly displaying their earned token quantities of their documentation, reinforcing the monetary motivation behind this coordinated, two-year operation.
